Reasons why water and wind erosion are diffrent.

Wind erosion is occurred when pieces of the earth are worn away by the strong winds. It occurs in dry bare areas when wind blows and moves the dirt around. Wind erosion causes damage to the crops by removing the soil which crops needed from it. Wind erosion can be prevented by soil tiling and by properly managing the crops.

Water erosion is the process where the piece of earth is worn away by water. It occurs at river banks or streams. Muddy water is the sign of water erosion. Water erosion is the more powerful erosion than wind erosion.

Wind erosion often occurs in dry areas and destroys crops. Water erosion occurs near bodies of water and is considered more powerful.

An 8 g bullet leaves the muzzle of a rifle with

Elena-2011 [213]

Answer: 1872 N

Explanation:

This problem can be solved by using one of the Kinematics equations and Newton's second law of motion:

$V^{2}=V_{o}^{2} + 2ad$ (1)

$F=ma$ (2)

Where:

$V=611.9 m/s$ is the bullet's final speed (when it leaves the muzzle)

$V_{o}=0$ is the bullet's initial speed (at rest)

$a$ is the bullet's acceleration

$d=0.8 m$ is the distance traveled by the bullet before leaving the muzzle

$F$ is the force

$m=8 g \frac{1 kg}{1000 g}=0.008 kg$ is the mass of the bullet

Knowing this, let's begin by isolating $a$ from (1):

$a=\frac{V^{2}}{2d}$ (3)

$a=\frac{(611.9 m/s)^{2}}{2(0.8 m)}$ (4)

$a=234013.5063 m/s^{2} \approx 2.34(10)^{5} m/s^{2}$ (5)

Substituting (5) in (2):

$F=(0.008 kg)(2.34(10)^{5} m/s^{2})$ (6)

Finally:

$F=1872 N$

Convert $25 in dimes<br><br> (I need explanation as well)

CaHeK987 [17]

Answer: To convert this into dimes it's basically like 25 divided by 10.

25 / 10 = 2.5, So you'd need two dimes and a nickel.

Musya8 [376]

Newton’s <u>first</u> law of motion states that "an object at rest will stay at rest, and an object in motion will stay in motion, unless acted on by an unbalanced force.

It is possible to consider Newton's first law to be the law of inertia. It helped us realise that when a body is at rest, it will remain at rest until an external force is applied to it, or if a body is travelling at a constant speed, it will stay moving until an external force is applied.

Only when net force is applied will a body move from its resting position. An illustration of this law can be seen when a passenger in a car fastens their seat belt. Both stationary and moving objects are covered by this law.
